COMBINATION TOOL.

Application led July 16,

This invention relates to combination tools, and its object is toprovide in a compact and and handy article a number of tools suitablefor carpentry, cabinet making and similar work.

A further object of the invention is to provide it with means for layingout or measuring special work.

A still further object of the invention is to construct the same inflat, elongated form, so that it may be conveniently carried in a long,narrow overalls pocket, like a folding rule.

A final, but nevertheless important object of the invention is toconstructV the same of few and simple parts and with no projections tocatch in the clothes or cause discomfort.

l/Vith the above objects in view, a better understanding of theinvention may be had by reference to the accompanying drawings, inwhich* Figure 1 is a perspective view of the appliance as viewed fromone side;

Fig. 2 is a like view, taken from the other side;

Fig. 3 is a longitudinal section;

Fig. 4 is a plan view illustrating the more common uses of theinvention;

Fig. 5 is a perspective view showing a cabinet installation requiring aspecial use of the tool;

Fig. 6 is a sectional group of the fittings used in the cabinetinstallation referred to;

Figs 7 to 1() are prespective views illustrating other instances of thespecial application of the tool; and

Fig. 11 is a section on line 11-11 of Fig. 1.

Referring specifically to the drawings, 15 denotes the stock of thetool, which is of flat 'steel and is adapted to contain the partscontributing to the various uses of the tool. One such part is an arm16, seated in a cavity 17 in one edge of the stock. One end of the armis perforated for pivotal motion about a screw 18 applied from one sideof the stock. The arm may thus be swung out to form a right angle withthe stock for use as a trysquare; or it may be fixed at any intermediateangle by tightening the screw 18 to form an angle or mitering gage. Theheel of the arm is square, as shown at 16, so that the arm may seataccurately at 90 degrees when swung at right-angles to the stock, and gono further, this adjustment being fixed by tightening the screw 18.

angles, readings are taken from a bow 19 carried by the arm and movingin a slot 20 in the stock. The bow 19 ispivotally attached with one endto the arm as shown at 21 and is foldable into a pocket 16b of the armwhen the tool is not in use.

The opposite or outer end of the arm 16 is tapered -and fitted with apoint 16c to serve as a compass with a companion arm 22 slidable in acavity 23 of the stock and stationed at any position by a set-screw 24.The outer end of the rod has a projecting point 22a for compass use; anda point 22b projects `from the side of the rod for use in conjunctionwith the stock as a scratch-gage. Also, the rod is forked at 22c toclear the bow 19 when in use.

The above constitute the common or ordinary uses of the tool, that is,asv a trysquare, angle or miter gage, compass and scratch gage. Thespecial applications of the tool will now be taken up.

Figure 5 shows a cabinet whose frame and door are fittedwithco-operating devices constituting a `spring latch to retain the doorwhen in closed position. This type of latch is widely used on talkingmachine, radio and other cabinets, but the method of preparing thecabinet frame and doors for the installation of the latch has so farbeen laborious and frequently inaccurate. The special features of thenovel combination `tool are designed to accomplish the work quicklyv andaccurately, so that the process becomes an eliicient one.

The co-operating fittings constituting the latch are shown more clearlyin Fig. 6, and comprise a keeper plate 25 carried by the door and aspring plunger 26 mounted in the ceiling of the cabinet. The keeperplate has an inclined approach 25a for the plunger, a depression 25b toseat the latter, and an aperture 25c in the depression to receive a nailwhen fastening down thev plate. The edge of the plate at the approach isfiat and alined with the inner edge of the door when the plate is laid.The plunger'26 is set in Va cup 26EL and backed by a lspring 26". j Thecup is driven into a bore 27 (see Fig. 9) in the ceiling of the cabinet,and the plunger yields to the plate when the door is closed.,

In preparing for the installation of the latch in a single door cabinet,such as in Fig. 9, it is generally found that the ceiling bore 27 hasbeen properly drilled before the assembly of the cabinet, so that it isonly necessary to match the site of the bore on the top edge of thedoor. To do this, a strip 28 slidable in a channel 29 in one edge of thestock 15 is employed. The strip is longitudinally slotted at 28a and isheld in place at any longitudinal adjustment by a screw 28b passingthrough the slot into the stock. The outer end of the strip has adowel-stud 28C projecting from its inner face. lli" hen the tool ispositioned and the strip extended over the door as per F ig. 9, the toolmay be tilted to hook the dewelstud 28c in the ceiling bore 27 as thedoor is almost closed. A pencil or Vscrew driver may now be inserted inthe slot 28FL to make a crossmark on the door. Vith this mark indicatedas in Fig. 10, an auger bit is applied so as to cut a shallow cavitybordering on the inner edge of the door, as denoted by the circulardotted line. A keeper plate can now be set in this cavity by a sharpblow of a hammer; and when a plunger unit is driven into the bore 27,the latch is ready for use. If the latch is found to function properly,the keeper plate may be permanently secured by a nail, as previouslymentioned.

The above operation applies to single-door cabinets in which the ceilingbore (27) for the plunger unit was found already made. In cabinetshaving double doors which meet at the center it is preferable to drillthe bores when the latches are fitted, and in this connection anotherfeature of the novel tool comes into use.

In the plotting of a center point for the ceiling bore of each door, twodimensions are considered, viz the distance from the closingedge of thedoor, and that from the closing face thereof. The tool is set for thesedistances, and then applied to the ceiling of the cabinet for themarking thereof. Taking the tool, it will be noted that beyond the heelof the arm 16, the stock is transversely bored at 30 to seat a slidableblock 31, stationed by a set screw 32. l/Vhen the block is inoutwardly-projected position and the arm 16 is set at right-angles tothe stock, as indicated in Fig. 8, the block is used as an origin fromwhich to space an aperture 33 in the arm. Different spacings may besecured by removing the pivot-screw 18 and setting the armsl oppositeanyone of a series of tapped holes 18a in which the screw may again beiitted. The stock may be graduated to denote the `spacing of the holes18a from the origin block 31. As to the arm aperture 83, its spacingfrom the edge of the stock corresponds to the spacing desired for theceiling bore center in an outward direction from the inner face of theclosed door. f

In order to plot the bore center, the toolwith the arm 16 closed but theblock 31 pro- -jected--is laid next inside the closed door and I flatlyagainst the ceiling, with the block 31 ing at the same time with onehand, the door is swung away with the other hand, and the arm 16 swungout, as shown in Fig. 8, An awl passed up through the aperture 33 willmake the proper center point in the ceiling.

The bore 27 may now be drilled and the balance of the work done in themanner described in Connection with the single door. To plot the centerpoint for the adjacent door, the tool is applied in the same fashion,but of course in inverted position.

The latch is marketed in two sizes, and for this purpose, an additionalarm aperture 33 is provided and properly spaced, to change the positionof the bore 27 relative to that which will be occupied bythediffe'rent-sized keeper plate.

A tool is thus had which is compact in form and contains a number ofunits which are applicable both to ordinary and special cabinet work.The stock is machined fiat and the setscrews sunken so that the sides ofthe tool will rave no projections to catch in the mechanics clothes. Forfacility, the scratch gage rod 22 will be marked with indications, sothat it may be accurately set to any position desired. Also, the setscrew 18 should be constructed in accordance with F ig. 11. The shank1Sn is threaded through one wall of the stock 15, then reduced to a stem1Sb which passes through the arm 16, and 'finally lodged in a recess 18cin the other wall of the stock. The shank thus bears with a shoulderagainst the arm when the screw is in the advanced position shown. Theto'p and recess in the walls are of course duplicated in a series forsetting the arm over in one or the other direction.
